Every March 14th we celebrate Pi Day, but this year is extra special because it only comes around once in a lifetime.

For those of us who use the Western Calendar, on March 14th, 2015 at 9:26 a.m. and 53 seconds we will experience a full 10 digits of the pi equation in a moment that won’t come around again for a hundred years. We even set this post to run at 9:26 a.m. EST to mark the moment. Very satisfying.

So enjoy it, Number Nerds, and have a slice of pie for us. Happy Pi Day!

Are you familiar with Winter-een-mas? It’s a gamer’s holiday that was started by Tim Buckley in the Ctrl+Alt+Del comic strip and it takes place over the course of seven days between January 25th and 31st. Each day is devoted to a specific genre:

January 25th: Adventure games, symbolized by a man dressed as Indiana Jones.

January 26th: First Person Shooter (FPS) games, with a 21 year-old sleep deprived gamer as its symbol.

January 27th: Fighting games, represented by a martial artist with too many blows to the head

January 28th: Real-time Strategy (RTS) games, whose emblem is a large bearded man with a pocket protector inside another pocket protector.

January 29th: Racing games, shown as a racer with old-fashioned racing helmet and racing goggles holding a detached steering wheel.

January 30th: Role Playing Games (RPGs), depicted as an elf-like woman holding floating dice above her left hand.

January 31st: Sports games, with a round, middle-aged man wearing a #10 jersey and holding a beer bottle in each hand as its emblem.

We don’t need much of an excuse to celebrate around here, so for the rest of the week we will feature a Winter-een-mas-themed shirt from our merch store, leading up to a giveaway over the weekend. Since today is the 27th, the shirt is all about fighting games.

The entire collection of shirts in our Nerd Approved Merch store (and TeePublic in general) are on sale for just $14 through the rest of the week. This includes hundreds of nerdy shirts from the best independent designers. The full breakdown looks like this:

Striker Eureka, the strongest and fastest mech on the planet, is the world’s only MARK V Jaeger.

Australia’s pride and joy is constructed of expertly crafted armor and finished with a detailed paint deco. Developed in partnership with award-winning filmmaker Guillermo Del Toro, the Sideshow Collectibles Striker Eureka statue brings this brutal brawler from the big screen to your collection.
